HIPPOLYTE IBERGERON, OF MONTREAL, QUEBEC, CANADA.

FURNACE.

Specification of Letters Patent.

Patented Sept. 30, 1919.

Application filed. January 16, 1919. Serial No. 271,401.

To all whom it may concern:

Be it known that I, HIPPOLYTE BnRennoN, a subject of the King of Great Britain, residing at the corner of Main and Forget streets, in the city of Montreal, Province of Quebec, Dominion of Canada, have invented certain new and useful Improvements in Furnaces; and I do hereby declare that the following is a full, clear, and exact description of the same.

The present invention relates to improvements in furnaces and the main object is to secure greater efficiency by increasing the heating surface of the furnace and reducing the cross-sectional area of the water passages.

A further object is to provide a furnace of simple and cheap construction.

The invention will be understood with the aid of the accompanying drawings in which,

Figure 1 is a front elevation of the furnace.

Fig. 2 is avertical cross-section through the furnace.

Fig. 3 is a side elevation with a portion of the wall broken away.

Like numerals of reference indicate corresponding parts in each figure.

In the drawings 1 is the base having the usual grate bars 2, ash pit 3 and ash pit door 4, said base supporting the vertical water sections 5 which are secured together by the horizontal stay rods 6 projecting through each section on each side and at the top, each stay rod having its front end threaded in a hole 7 provided in the front section and its rear end secured in the rear section by the nut 8.

Each water section 5 is provided with a number of superposed dome shaped water columns or sheets 9 communicating with the side water legs 10, and between the said water columns, an inner flue 11 is provided communicating with the outer flue 12 by means of the opening 13. The flue 11 communicates with the top portion of the main flue 14.

As illustrated in Fig. 2,the water columns 9 are so shaped as to provide a fire box 15 which is surrounded by the water legs 10.

The front water section 16 is preferably provided with a fire box opening communieating with the fire box, and closed by the door 17.

Above said door 17 is provided a smaller opening, and 18 is a door for closing said opening. On each side of said door 18, is provided a curved door 19 suitably hinged and adapted to cover or close the flues 11 and 12 in the section 16, which communicate with the corresponding flues in the sec-- tions 5. To clean these flues the doors 19 are opened, whereupon said flues are readily accessible.

The rear section 20 is provided with the dome shaped water columns 9 and flues 12 communicating with the corresponding flues in the sections 5, 21 is a rear water leg communicating with the water columns 9 and provided at its lowermost end with the water inlet 22, and 23 is a pipe communicating with all of the flues 12 and leading to the chimney.

One of the sections 5 is provided at its uppermost end with a water outlet 24-.

The invention will be easily understood from the foregoing description, but it may be said that the furnace may be quite easily heated by crude oil in the place of coal, by simply employing one or more burners in place of the grate 2, without departing from the scope of the following claim for novelty.

What I claim as my invention is:

A. furnace comprising a series of water sections connected together and constructed to form a central fire-box, a pair of vertical water legs at opposite sides thereof, a pluumns directly superposed over the fire-box and communicating with each other intermediate their ends and with the water legs at their ends, a main flue disposed over the fire-box and into which the latter directly opens at its top throughout its entire length, dome-shaped inner and outer flues interposed between the water columns, the inner flue communicating along its median portion with the top part of the main flue and along its sides with the outer flue, and an outlet pipe into which the outer flue opens, one of the sections having a water outlet and one end section having a water inlet. S1gned at Montreal, Canada.
